Device
Quadrature balanced N-path receiver (QBNR) for frequency division duplex (FDD) with two-port N-path (TPNP) filters manufactured in 65nm CMOS
Spectrum
1.5 GHz
Novelty
Two-port N-path (TPNP) filter in an auxiliary signal path fully cancels transmitter-induced reciprocal mixing noise at the receiver under any antenna VSWR.
Application
Integrated SAW-less FDD systems.
Performance
10 dBm TX power handling, 0.5 – 2.5 dB noise figure (NF) degradation
